3. Set the Pressure / Flow Rate Display to read in either PSI or kPa (see
Normal Operation, Selecting the
Pressure / Flow Rate Display and Units
).
4. Remove the insulation covering the pressure regulating valve cap and then remove the cap. There may
be some coolant in the cap; this is normal.
5. Loosen the locknut and then using a flat blade screwdriver, adjust the pressure until the reading on the
Pressure / Flow Rate Display matches the desired maximum operating pressure. A clockwise rotation
increases pressure; a counter-clockwise rotation decreases pressure.
6. Set the minimum allowable flow rate to the desired value.
7. Tighten the locknut and replace the cap and insulation.
8. Set the Pressure / Flow Rate Display to the preferred reading (GPM, LPM, PSI, kPa).
